On this site, finite element models of full vehicles can be found and downloaded free of charge. The site is operated by the Center for Collision Safety and Analysis (CCSA), formerly known as National Crash Analysis Center (NCAC).
Crash and occupant safety analysis software must be able to handle large deformations, sophisticated material models (for steel and aluminum, rubbers, foams, plastics, and composites), complex contact conditions among multiple components, and short-duration impact dynamics. The software must be capable of simulating different types of car crash events: frontal impact, side impact, rear impact, and rollover.
